A Survey of Security Threats on 4G Networks

Many communication societies such as ITU and IEEE are working on 4^th generation (4G) communication. This paper provides an overview of standardization activities focusing on the network security architectures and a survey of security threats on 4G networks. Our survey shows that a number of new security threats to cause unexpected service interruption and disclosure of information will be possible in 4G due mainly to the fact that 4G is an IP-based, heterogeneous network. We also found there still remain several open issues although many are working on fixing and/or designing new security architectures for 4G.
